Climate Change Experiment LAB — Background Overview Educated citizens need to understand how scientific investigations are done and how results and
conclusions are reported in order to make informed decisions. What is experimental evidence? What is
hypothesis testing? How do scientists evaluate data and draw conclusions? Educated citizens also need a
basic understanding of climate change. In this lab, we are going to watch a video fieldtrip of the
Asymmetric Warming Experiment at the Environmental Protection Agency (EPA) in Corvallis, which
uses precision climate-controlled chambers called “terracosms”. After watching the video, you will
answer questions to help guide you through understanding how the experiment was designed. The
purpose of this lab is to refresh your memory and understanding of the scientific method and ecology
while learning how scientists study climate change.
BE ORIGINAL! Remember to use your own words and do not copy verbatim from any online,
previous or current student source. By submitting this assignment, you are agreeing to the
following statement: “I understand that my paper will be checked against multiple sources for
original content. A report will be generated that shows if content in this paper matches content in
documents available on the Internet, in many print journals, and a database of other papers
submitted by students. If submitted to the instructor, my paper will be added to the student
database for comparison of future OSU papers against it. I maintain ownership of the original
intellectual property created in this paper. I understand that results of this report may be used by
the University in student conduct proceedings related to academic dishonesty (See Canvas Start
Here module for more information)” Turnitin generates a report that highlights any potentially
unoriginal text in your paper, including text from previous students’ or current students’
Learning Outcomes Assignment Outcomes
• Explain how plant photosynthesis, respiration, and growth can vary with temperature.
• Describe how rates of plant photosynthesis, respiration, and growth can affect atmospheric carbon dioxide levels
• Evaluate hypotheses and experimental design in a climate change experiment.
Module Outcomes 4. Summarize how researchers study climate 5. Outline current and future impacts of global climate change
Course Outcomes C1. Recognize and apply biological concepts and theories in complex, interdisciplinary
environmental and sustainability problems.
C2. Explain and predict effects of pollutants on ecosystems based on ecological principles
C5. Read and interpret graphs and data, and explain sources of uncertainty in scientific data and
environmental model predictions
C6. Describe the process of conducting responsible, professional science.
Background The assigned readings and lectures will provide the background information for this lab.
In this assignment, you will watch the virtual field trip to the EPA terracosm experiment, and use the
information to answer the questions in the assignment.
